STREET=CLEANNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 295x188, dated April 8,188%.

Application filed Septeinbor .28, 18853. (No model.)

'or keeping the water and air-lhot, and also of the special constructionof the machine, whereby it may be easily controlled, and whereby it ismade practical for its purposes.

Reference is to be had to the accompanying drawings, forming part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is-a side elevation of my new and improved street-cleaningmachine erected on a truck, one of the rear wheels of the truck beingremoved. Fig. 2 isa plan yiew of the machine and truck. Fig. 8 is a rearelevation of the machine and truck. Fig." l is a de tailed sectionalelevation ofthe water and air distributor; and Fig. 5 is a detailedsectional plan view of the central vertical hand-shaft and chains forswinging the distributor to the one side or the other, to avoidobstructions at the sides.

A is the water-tank, here supported upon the rear axle of a suitablecarriage or truck.

B is the compressed-air tank, supported upon the forward axle of thetruck, which tanks are constructed to sustain any required internalpressure; and G is the distributer, here consisting of closed pipes, thelarge pipe 1) and smaller final distributing-pipe 1* which latter isconnected with the pipe 1) by the pipes or hose a, c and rods 1) 2), andis carried by the latter near the pavement, as shown. The pipe D isconnected with the tank A by means of the flexible pipe (I, valved at d,and the final distributing-pipe E is providedwith theseries of nipplesor apertures c c, for dividing the water into small streams as itlpassesfrom the tan; to the surface of the: street. The compressed-air tank Bis connected with the watertank A by means of the pipe 1'', which isprovided with the cock 0, which regulates the flow of compressed airfrom the tank: I to the tank A.

In some cases the machine will be operated with thedistrilniting-pipes 1) 1? parallel with the rear axle of the truck, asshown in Fig. 3, while in other cases these pipes will be carried at anangle to the axle, as shown in Fig. 2, for working the dirt of thestreet toward the curbstone.

In order that the pipes 1) 10 may be set at any desired angle forsweeping the dirt toward the cnrbstone on the right or the left, and beswayed to the one side or the other of the truck, to avoid obstructionson the side, I attach the pipe 1) to and parallel with the rearcrossbar, H, of a parallel frame, the central bar, F, of which iscentrally pivoted to the truck or carriage, and is provided with thewinding-shaft g and chain 1 which is attached at its ends to the sidesof the truck, and passed around the said winding-shalt in oppositedirections, as shown in Fig. 5.

The side bars, G (.r, are adapted to slide in the truck or carriage, andare pivoted at their ends to the ends of the cross-bars H ll, whichcrossbar-s are centrally pivoted to the ends of the central bar, F.These side bars, (l- G, are each provided with a whirling-shaft, j j,and chains jj, which are fastened to a collar around the center pin, bywhich the cent 211 bar, F, is pivoted in the truck, as shown in Fig. 2.TVith this construction, to set the distributor at an angle, the pipe I)being attached to the rear bar, H, of the parallel frame, it isonly'necessary fora person standing on the rear plat form, J to turn oneof the wimling-shafts j, thereby shortening the corresponding chaiinj,the other chain being slack, thereby sliding one of the sidebars, (l,farther under the truck or carriage and the other side bar farther tothe rear, thereby securing the angle desired,

when the chainsjj are both made taut. They are thus held by a suitablepawl and ratchet applied to the said shal'tsj j.

To bring the pipes D E back in line with the axle of the truck, or toreverse the angle at which they are set, it is only necessary to eperateas before, except i 0 turn the other winding-shaft j.

.along either ahead of In case cold water alone is to be used forleaning the street, the tank A will be filled .vith water through theshort pipe 7i: and the pipe closed by the cock It, and the tank .& willbe charged with compressed air up to the required pressure through theshort pipe Z, and the pipe closed by turning the cock Z. The machinewill then be taken to the work and the cocksd and 0 opened, which will.admit the water from the tank A to the pipes I) E and the compressed airto the water-tz'mk A, where it will exert a pressure on the surface ofthe water in the tank, and cause the water to pass out of the nipples cc in the pipe E with great force. The nipples c c are set at.

an angle to the plane of the street, as indicated in Figs. 2 and 4., sothat the streams of water discharged from the nipples will strike thesurface ofthe street in the most effective way for loosening andremoving the dirt, and so that the dirt of the street will be forced thepipe lb] or carried toward the curbstone in case the pipes l) and E areheld at an angle to the machine, as above described.

\Vithin the pipe E is held the smaller pipe, K,which. is furnished withas many smallnippics p as there are nipples c in the pipe E, whichnipples p .reach into the nipples c, as shownin Fig. 4, and this pipe K.is connected by means of the pipe II) with the compressed air tank ll,and this pipe L is provided with the cock m, which cock, in case waterand air are to be used in conjunction for cleaning the street, will beopened sinniltaneously with the opening of the cooks c and d.

In case hot water is to be used in the machine for clearing away snowand. ice from the streets, the machine will be provided withthe furnaceN, through which the water from the tank A will pass on its way to thedistributer through the pipe J, whichleads from the bottom of the'insideof the tank through the furnace and connects with the piped, as shown inFig.1.. \Vhen used in this manner, the cock (1 will be kept closed,while the cocks h h in the pi pe J will be opener and the compressedair-when the machine is used for meltinginstead of being permitted topass through the pipe f to the tank A,'will be caused, by closing thecock 0 and opening the cock 0, to pass through the pipef, which passesthrough the furnace, so that the compressed air will be heated in thefurnace before entering the tank A.

The pipe 1') is adapted to be elevated when the machine is not in use,or while it is being taken to and from work, by means of the arm N,attached to the pipe 1), and the lever N, fulcrumcd in the platform J,the arm and lever being connected together by means of the chain 1(shown in Figs. 1, 2, and 3,) and the pipe I) being adapted to turn inthe collars i i t, by which it is attached to bar H. The pipe E isadapted to be turned in Lthe collars t '1", by which it attaclual to therods 11 b, for changing the position of the nipples c c,-for varying theangle at which the jets of water or water and air will strike thesurface of the street.

In operation, the tank A having been filled with water, and the tank Bcharged with compressed air up to a pressure, say, of three hundredpounds to the square inch, and the nipple adjusted to suit the work tobe done, the proper valves are then opened and the machine is drawn.over the street. Now, as the truck moves along, the pipeE is brought upto the work before it, and the jets of water, or water and air, strikingforward with great force and at a low angle to the pavement, sweep thedirt before them, and, when the distributer is set at an angle, as shownin Fig. 2, shovethe dirt to one side at the same time. \Vhen wa- WV henthe ter and air arcb'oth expressed from the nipples at the same time,the effect will be the same as when water is used alone, but less waterwill be required. The tank B will ordinarily be charged with compressedair by an air-compressi 11 machine,- but where the waterpressure in thehydrant is sufficient, no compressor need be used, the pressure in thehydrant being utilized in charging the tank and the compressed airconserved so as the air-tank at each filling of the water-tank in thismanner-supposing the pressure in the hydrant to be thirty pounds,sufficient to elevate water sixty feet in an open tube, and that fifteenpounds be sufiicient to work the machine. The cocks being all closedexcept the cock Zr, the hydrant is connected by means of a hose to thepine 7. The cock 0 is now to be opencd, so thz t the air in tank A maypass to tank 13 as tank A becomes filled with water. tank A is full ofwater, the tank B will containtwo atmospheres. The cock e is I nowcloscd and the water in tank Adrawn off. The tank A is then againconnected with the ,hydrant, and the cock 0 opened and the watertu1'nedon, a1nl when the tank A is full the tank B will containthreeatmospheres, when the cock cwill. be again closed, the water again andI3 is equal to the hydrant-pressure, care being taken to turn the cock 6before stopping the water-flow, and opening this cock afteragainconnecting the hydrant.

There the deficiency of hydrant-pressnre is not too great, thedeficiency of pressure in the tank 1 may an air-pump.

Having thus fully described myinvention, I claim as new and desire tosecure by Letters l.atent I l 1. The wate discharge pipe 19, providedwith the seriie oi 'n'pples 0, and the inclosed pipe K, pi-e'v' led withthe nipples 7 in conibination with the tank A. and tank 13, said Zanksconn t d, respectively, with pipes E nd K, sub tait ally as and for thepurpose set forth.
